WILLIAM W. WINGER, OF WOLCO'IT, INDIANA.

DRAFT APPLIANCE.

To all whom it may concern:

' Be it known that I, WVILLIAM W. IVINGER, a citizen of the UnitedStates, residing at lVolcott, in the county of White and State ofIndiana, have invented certain new and useful Improvements in DraftAppliances, of which the following is a specification.

This invention relates to draft appliances of that type adapted for useespecially upon agricultural implements, and relates specifically to animprovement upon the draft appliance patented to me on Sept. 28, 1909,No. 935,135.

For a full understanding of the invention reference is to be had to thefollowing description and the accompanying drawings, in which Figure 1is a perspective view of the principal parts of the invention in normaloperative position; Fig. 2 is a partial plan view, partly in section,and with the crank member turned to an angle to the normal position, andFig. 3 is a vertical section substantially on the line 33 of Fig. 2.

Throughout the following description and on the several figures of thedrawings similar parts are referred to by like reference characters.

At 10 is indicated what may be regarded as a plow beam, to the front endof which are connected a pair of clamp members 11 and 11, said membersembracing said beam end. A pivot 12 passes through the rear end of theclamp members, whereby the said members may be adjusted vertically withrespect to the beam. A bolt. 13 passes through any one of a series ofholes 11 of the pairs of clamp members and the extreme end of the plowbeam, for securing the clamp members at any desired degree of elevation.Each clamp member comprises a pair of jaws 1 1 at its forward end,between which is a horizontal space of any desired form, preferablycylindrical. A tubular draft bar 15, shown as cylindrical, is securelyclamped at one end within said horizontal jaw spaces, by virtue of bolts16 which pass vertically through the respective pairs of jaws 14. Adouble armed crank 17 is journaled in the draft bar 15, the cranks 17and 17 of which extend at right angles Specification of Letters Patent.

from the opposite ends of the main portion of said crank in oppositedirections and preferably in the same plane. The arms may be of anysuitable lengths, the arm 17 being shown as longer than the other. Afulcrum bar 18 is secured to the draft bar 15 at one side of the clampmembers and preferably substantially midway between the ends of thedraft bar. By virtue of a bolt 19 the fulcrum bar may be adjustablyclamped at any desired angle upon the draft bar and also at any suitabledistance from the aforesaid beam clamp members. A pair of draft levers20 and 21 are pivoted together at 22 and to the front end of the fulcrumbar 18. Said draft levers are respectively connected by clevises andlinks to the crank arms 17 and 17". Any suitable number of horses may beattached to the outer ends of the draft levers 20 and 21.

The several parts of this device may be made of any suitable materialsor relative proportions. I do not wish to be limited in the use thereofto the exact construction illustrated.

I claim:

1. In a draft appliance, the combination with a beam, of a pair of clampmembers embracing the end of the beam, means to connect said members tothe beam whereby the front ends of the members may be adjusted up ordown with respect to the beam end, each of said members comprising apair of jaws with a horizontal space therebetween, a draft baradjustably clamped at one end in the horizontal spaces of said clampmembers, a double armed crank journaled in said draft bar, and a set ofdraft levers connected to the crank arms and to the draft bar,substantially as set forth.

2. I11 a draft appliance, the combination with a beam, of a pair ofclamp members pivoted at their rear ends to opposite sides of the beam,means to adjustably secure said members from pivotal movement, each ofsaid members having a pair of jaws at its forward end with a horizontalcylindrical space between the jaws, a cylindrical tubular draft baradjustably clamped in said jaw spaces, a double armed crank journaled insaid draft bar, a fulcrum bar adjustably clamped to the tubular draftbar at one side of the clamp members aforesaid and extend ing forwardlyfrom the draft bar, and a pair of draft levers pivoted at their adjacentends to the front end of the fulcrum bar and also connected to theseveral crank arms, substantially as set forth.

In testimony whereof I afiix my signature in presence of two Witnesses.
